MODE or PREVENTING THREAD EEoM GOING To WASTE IN MAcHINEEY OE DOUBLINGAND TWIS'IING SEWING SILK, woEsTEE, coTToN, AND LINEN THREAD.

Specification of Letters Patent No. 352, dated August 15, 1837.

To all whom it may concern Be it known that I, JOHN GOLDING, of Dedham,in the county of Norfolk and Commonwealth of Massachusetts, on theeleventh day of March, A. D. 1837, and now this. 20th day of July, A. D.1837, a resident of Mansfield, in the county of Tolland and State ofConnecticut, did on the said 11th day of March, A. D. 1837, invent a newand useful Improvement in Machinery for Doubling and Twisting SewingSilk, Worsted, Cotton, and Linen Thread, and that the following is afull and exact description.

The nature of my invention, is the application of machinery to adoubling and twisting frame to create a motion whlch will prevent thethread from running to waste, should the attendant be absent, the motionto be governed by the breaking of the thread.

To enable others skilled in the art, to make and use my invention,(Section I) I construct the frame in any of the modern forms with gearsand an eccentric or heart motion thereto attached to guide the thread onthe spool.

The following is a full description and operation of what I claim to bethe inventor of, as in improvement, to the machinery for doubling andtwisting to obtain the mo-- tion to prevent the thread from running towaste (viz) Instead of a common cylinder in (Section II) the center ofthe frame, which turns the spindle I put a shaft, with pulleys thereon,said pulleys are in couples, one is stationed on the shaft, the otherloose also apply thereto feeding down rollers (and spindles mounted inthe known manner) instead of the top feeding down-roller beingstationary; on the under one, I put on a hanger, supporting it fixedwith a loose joint, at the lower end, which is to be raised or loweredby moving of levers as hereafter described. (Sect-ion III) I place onthe frame to each spindle three levers and a shaft, with a crank on eachend, one balance lever on the upper part of the frame; which isoverbalanced by wires No. 2, a shaft running the length of the frame,which revolves No. 9 placed at the end of lever No. 8 with a tooth orcog projecting out of the shaft, pointing to the end of each balancelever No. 8. On the other end of the balance lever I place aperpendicular lever No. 11 supported by a stud on the girth one-thirddisspool or spindle No.

tance from the bottom. The bottom of this lever is connected with ahorizontal lever No. 15 which 1s placed with a stud in the center onanother girth, the other end of I this lever is linked to the'lo-osepulley No. 16, to the perpendicular lever, twosteel springs are fastenedone on each side projecting upward.

I then connect one of the springs to" crank No. 18, which is on a shaftNo. 12,

that runs crossways of the frame supported by two girths under thebalance lever the other spring is secured to the girth, on the end ofshaft No. 12 a similar crank 14; which is stationary on shaft No. 12, tothis crank I connect a wire, and hook it up to the roller hanger No. 18,moving the perpendicular lever to the left, slides the loose pulley No.

16 in couple, and at same time drawsdown the roller-hanger No. 18 andsets the spindle to which the thread is attached, in this operation Isecure the perpendicular lever No. 11 from flying back, with a latch,No. 10, which lays over a pin projecting out of the upper end of leverNo. 11 by ralsing up the latch, the spring lever will fly to the right'and slide the loose pulley out of couple which stops the spindle andraises the top roller. (Section IV) I then take the-thread from thespool No. 1 and raise up the lever wires No. 2 which lays over thebalance lever No. 8. I put a thread through each wire drawing them overthe glass case No. 3 then draw them both together through the guide wireNo. 4, thence between the feeding down roller No. 5 through the lowerguide wire N0. 6 and fasten the thread to the 7. I take hold of thespringlever No. 11 and slide to the left and secure by latch No. 10,this draws down roller-hanger at same time slides loose pulley No. 16 incouple which puts the spindle No. 7 to which the thread is attached inmotion.

In case the thread breaks the lever wire No. 2 drops and falling on aprojecting wire on balance lever No. 3 and over balancing the lever,will bring the end in contact with the tooth or cog projection from therevolving shaft No. 9, this raises the opposite end of the lever; priesup the latch No. 10, which unhooks the perpendicular spring lever No.11, this flies back, draws crank No. 13, which is stationary on shaftNo. 12 toward it; this gives an upward vmotion to crank No. 14:; at theother end of shaft No. l2,'being con.- nected by a wire withroller-hanger No. 18 raises the upper-feeding-down-roller and stops thethread from drawing down. The lower end of perpendicular lever No. 11being, connected with horizontal lever No. 15 slides the loose pulleyNo. 16 out of couple, and stops spindle No. 7, thus by a thread breakingstops the spindle to which the thread is attached and throws up thetopfeeding-down-roller, which stops the thread from drawing down andentirely prevents waste.

hat I claim asmy invention, and desire to have secured by LettersPatent, is-

The machinery described in this applica-v tion, in sections Nos. two andthree and operetion, described in section No. tour, which arrangement ofmachinery, by the breaking 20 roller by the breaking of the thread topre- 30 vent waste.
